The measurements of five low molecular weight chlorinated hydrocarbons (LHCHs) were performed in the air and sea water of Osaka Bay in 1977. The average concentrations of sea water were 19, 56, 150, 140 and 690 ng/l for carbon tetrachloride, chloroform, trichloroethylene, tetrachloroethylene and 1,2-dichloroethane, respectively. The average concentrations of the air samples were 4.1, 5.3, 6.7, 7.6 and 8.4 µg/m<sup>3</sup> for carbon tetrachloride, chloroform, trichloroethylene, tetrachloroethylene and 1,2-dichloroetane, respectively. These results indicate that LMCHs are ubiquitous in the sea water and air samples. And these levels were (10-100) times for sea water and (2-50) times for the air higher than those of other areas of the Seto Inland Sea. According to the estimation of the fluxes of LMCHs across the air-sea water interface using two-layer model, (6.9-81) tons of LMCHs transfer from sea water to the air in a year. These fluxes are nearly equal to the amounts of LMCHs carried from rivers in Osaka Bay. This result suggests that almost of the LMCHs entering to the Osaka Bay from river diffuse to the atmosphere through the air-sea water interface and do not residue in sea water body.
